HIP6601_04 INTERSIL [Intersil Corporation], HIP6601_04 Datasheet - Page 7

• Manufacturer Part Number: HIP6601_04
• Description: Synchronous-Rectified Buck MOSFET Drivers
• Manufacturer: INTERSIL [Intersil Corporation]

Since both upper and lower gate capacitance can vary, Figure 7 shows dissipation curves versus lower gate capacitance with
upper gate capacitance held constant at three different values. These curves apply only to the HIP6601 due to power supply
configuration.
